DIEGO MATTE I, OF GENOA, ITALY.

SPECIFICATION forming part of Letters Patent No. 746,863, dated December 15, 1903.

Application filed March 17, 1903- Serial No. 148,250. (No model.)

To all whom it may concern:

Be it known that I, DIEGO MATTEI, mechanical engineer, a subject of the King of Italy, residing at 22 Via Almeria, Genoa, Italy, have invented certain new and useful Improvements in Apparatus for Dyeing (lard- Slivers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention refers to certain improvements in the apparatus for dyeing card-slivers, forming the object of my Patent No. 705,856.' Said improvements are designed to obtain anapparatus as efficient as that protected by the aforesaid patent in as far as concerns the continuous impregnations of the cotton slivers with liquid and the dripping of the impregnated cotton into the dye-baths without the slivers becoming disaggregated by the action of viscous or high alkaline baths. According to my aforesaid patent this difiiculty is met by the use of perforated carrierbelts, which support the sliver during the whole of the dyeing operations, relieving any stress therefrom. The provision of the said carrier-belts is practically efiicient, but rene ders the machine to a certain extent expensive and complioatedl By the employment of the present improvements the said carrierbelts in the dye-vats are entirely done away with and the machine rendered thereby'm uch simpler and cheaper. In order to describe the same, it will be well to review the different operations which are to be performed in order to carry out the dyeing of the cotton slivers. They are as follows: first, impregnating the slivers with water or dye; second, squeezing the same to expel said water or dye; third, dipping the sliver into a dyebath if the sliver was previously impregnated with water; fourth, conveying the sliver and collecting the same, impregnated with dye, intoreceptacles which may be heated by steam or contain a dye in order to fix the dye upon the fiber, and guiding said sliver to devices adapted to again'impregnate, squeeze, and convey the same in order to repeat the same operations as set forth under headings second, third, and fourth as many times as are necessary, according to the number of baths which the sliver.

the sliver is to go through, depending upon the shade of the color which is to be imparted thereto; fifth, washing and finally squeezing and winding the sliver in the form of disks or cheeses.

In the accompanying drawings, in which I have illustrated an embodiment of my invention', and in which like reference characters indicate similar parts throughout, Figure 1 is a plan view showing the general arrange ment of the apparatus. Fig. 2 is a front elevation of Fig. 1. Figs. 3, 4, and 5 are side views of different sections of the apparatus. Figs. 6 and 7 are longitudinal and transverse sections of a form of injecting device. Figs. 8 and 9 are longitudinal and transverse sections of a modified form of impregnating device. Figs. 10.and 11 are longitudinal and transverse sections of a dyeing-tank. Figs. 12, 13, and 14 are an elevation and sectional detail view of the conveyor. Fig. 15 represents in detail the clutch mechanism; and Figs. 16 and 17 represent, respectively, an elevation and a detail view of the stop-motion device.

Impregnaiiow-The impregnation is carried out in diiferent ways, depending upon its taking place either with water and with liquids which may be used in excess, or with liquids which are so expensive as not to allow of their being used in a greater quantity than strictly required. In the first case the injector intended to carry out the impregnatiou, Figs. 6 and 7, consists of a hollow cylinder 1, provided with only one bottom and revolving around axis 2. Holes 3 are pierced through its shell. Cylinder 1 is surmounted by a metal case 4, the bottom of whose compartments 5 and 6 exactly fit to the external shape of cylinder 1, only leaving a space of about one and one-half millimeters depth along the perforated part of the cylindershell, such space constituting a passage for The bottom of the compartments 5 and 6 is pierced with holes or slits. Gompartment 5 receives steam through pipe 7, while compartment 6 is connected with a reservoir of water under pressure. The case 4 hangs from a pivot 9, which prevents it from being turned by the revolving cylinder '1, toward which it is pressed by. the weight 8. Within the hollow cylinder is a perforated pipe 10, which also receives water under pressure and whose perforations correspond to those of compartment 6 of the case 4.

In case the sliver is to be impregnated with expensive dyes the injector whereby this operation is to be carried out takes the form shown by Figs. 8 and 9, in which 11 is a metal trough, 12 a metal cylinder, like cylinder 1, Figs. 6 and 7. 13 is a case similar to 4, but having only one compartment connected with a steam-pipe. 14 is a cylinder of the same diameter as 12, having overhanging bars 15 and having its axis somewhat higher than that of cylinder 12. 16 is a solid cylinder of the same diameter as 12 and 14 and having its axis still higher than that of cylinders 12 and 14. The cylinders 16, 12, and 14 revolve almost in contact with and impart motion to each other by means of spur-wheels 17. A floating body (not shown in the drawings) keeps the trough filled with dye-bath up to a level 18, slightly higher than the lowermost edge of case 13.

Wrqlnging out-This operation is carried out by means of pairs of wood rollers, one of which-namely,the upper oneis coated with rubber.

Dipping into the dge-bath.The apparatus by means of which the sliver is dipped into the dye-bath and impregnated therewith consists of a small trough 19, Figs. 10 and 11, capable of revolving around the axis 26 and communicating by means of a pipe 21 with a floating body 20, Figs. 1 and 2, supplying it with dye-bath flowing from the tanks 60, Figs. 1, 2, 3, and 4, and kept at a constant level. A cylinder 22, Figs. 10 and 11, fitted with bars at its surface and similar to 14, Fig. 8, is revolving within the trough 19. The upper cylinder 23 is either hollow and perforated or provided with very thin longitudinal flutes at its surface. It has the same diameter as 22 and revolves almost in contact with the same, but at a higher level. Cylinders 22 and 23 also gear with each other by means of spur-wheels 17.

24 is a guide-roller, and 25 a squeezing or wringing-out roller.

Both the trough l9 and the bar-cylinder 22 are adapted to revolve around axis 26 and are kept into contact with 23 by means of the springs 27,connectedwith thetnachine-frame, said. springs being intended to prevent breakages in the case of the slivers getting entangled around either 22 or 23.

28 is a tube or sleeve surrounding the axle of cylinder 22 and preventing the fibers, which may float in the dye-bath, from being wound round the said axle duringits rotation.

In lieu of bar-cylinders 14, Figs. 8 and 9, and 22, Figs. 10 and 11, hollow cylinders pierced with holes or fitted at their surface with large longitudinal flutes or pairs of front disks connected with longitudinal bars like squirrel-cages may also be used.

Convey-ing and collecting the sliver -The conveying and collecting apparatus consists of a metal vessel, Figs. 12, 13, 14, preferably U-shaped, the upper portions of the U-stems being strongly inclined to the vertical. Each side of the vessel is provided with slots 30, Fig. 14. A continuous rubber belt 31, whose stiffness in transverse direction is secured by wooden cross-slats 37, engaged with the ends of said cross-slats 37 in the slots 30, passes around the rollers 32 and 33 and takes its way outside on the tightening-rollers 39. The vessel is fitted with a removable lid 36 and may be heated by steam through pipe 38. The vessel mayalso be heated by means of a steamcoil or a double bottom. This conveyor materially differs from that covered by my former patent, No. 705,856, in that it is fitted with one instead of two guiding-belts, whereby all inconveniences arising from the stoppage of one of them or a, difference in their speeds are avoided.

34 and 35 are rollers by which the sliver is caused to regularly accumulate on the belt 31.

The general arrangement of the machine. The machine consists of a number of sections quite similar to each other, whose number only depends on the number of dye-baths which the sliver is to pass through. Four sections are sufficient in most cases, and they are shown as I, II, III, IV in Figs. 1, 2, 3, 4 of the accompanying drawings. Section V, Figs. 1, 2, 5, is only intended for washing, wringing out, and finally winding the slivers when dyed. The slivers take a zigzag path through the various sections, which are connected with each other by means of the collecting and conveying apparatus 40 41 42 43. The driving-shaft 44 is mounted at the upper part of the machine in a direction perpendicular to that of the various sections. The same is driven by means ofafast and loose pulley 45 and causes the various parts of the machine to revolve through chain-pulleys 46, mounted on couplings 48, Fig. 15, fitted with clutches 49, arranged fox-disengaging. Each section may therefore be stopped without interfering with the other ones. Each coupling is fitted with a self-acting disengaging device 50, putting the corresponding section out of action in the case of undue resistances arising in order to prevent possible breakages. On the longitudinal joists of the difierent sections the different parts are arranged as follows:

Section I, Fig. 3: (a) A stop-motion R, of

any well-known construction, which puts the whole section out of action should a sliver get broken; (1)) an impregnating device S, like one of those shown in either Figs. 6 and 7 or Figs.

8 and 9; (c) a pair of wringing-out rollers P;

" cess.

and the second one;) (1)) dye-bath trough U; (0) reel for arranging the sliver in folds.

Section V, Fig. 5, consists of (a) wringingout rollers P, with water-jets G for the purpose of washing; (b) winding apparatus.

The working of the machine is as follows: Six or seven card-pots are set before the feeding end of section I. The slivers contained therein pass along a guide-plate on the stopmotion R, Figs. 16 and 17, consisting of blades 53, journaled at their middle, spoonshaped at one end, while from the other end thereof hangs a plate 54, provided with a recess. As long as the spoon-shaped end is being held down by the tension of the sliver gliding thereon the continuously-revolving blade 55 is free to enter the recess of' plate 54; but as soon as the sliver breaks the weight of the plate 54 causes the blade 53 to turn, and the plate 54 falls down, whereby the part which has no recess is brought opposite the blade .55, which on revolving shifts lever 56 toward the left and removes the stop 57, whereupon the weight 58 is allowed to fall down and draws with it the starting-lever 59, Fig. 3, causing the whole of the section to stop at once. On leaving the stop-motion theslivers pass to one of the impregnating devices S.

(Shown in either Figs. 6 and 701' Figs. Sand 9.) In the first case they enter the space between the perforated cylinder 1 and the cased. The sliver resulting from the coupling of six or seven elementary slivers following the motion imparted to it by cylinder 1 is struck first by the jet of the steam flowing through 5, which expels all the air from the fibers, and later on by the jets of water flowing through both 6 and 10, which condense the steam and leave the fibers thoroughly impregnated with liquid. If the impregnating device resorted to is of the description shown, Figs. Sand 9, the slivers after having passed between 12 and 13, whereby the air is thoroughly expelled by the steam-jet flowing through 13, are wound round the bars-cylinder l4 and compelled to dip into the dye-bath, which condenses the steam, takes its place, and thoroughly impregnates the slivers. On leaving cylinder 14 the sliver goes on to cylinder 16, by which it is delivered to the wringing-out rollers. The level of the liquid within the trough 11 must be such as to cover the edge 18 of case 13 in order to prevent fresh air from again entering the'fibers of the sliver, and to allow the same to get fully impregnated with liquid. On leavingthe wringing-out rollers the sliver is sufficiently tough to admit of its going over to the roller-guide 24 of the dipping apparatus U, Fig. 10, wherefrom it proceeds to the bars-cylinder 22, which dips it into the dye-bath and delivers it to cylinder 23 when the roller 25 has wrung out the liquid in' ex- On leaving cylinder 23 the sliver, by means of reel 52, is arranged in regular layers or folds between the rollers 32 and 34 on belt 31 of the conveying device, Fig. 12. 4:7, Figs. 3and 4, is an oscillating plate controlled by the reel, the'function of which is to press down the folds of the sliver as arranged by the reel in order to obtain a regular pile of folds. The slow motion of the continuous belt 31 as controlled by the rollers 32 and 33, driven by chains and endless screws in any known manner, causes the cotton collected upon the belt to proceed toward the succeeding section. During said passage the dye fastens on the cotton, which may be meanwhile steamed. On reaching the opposite end of the vesselnamely, the rollers 33 and 35the sliver is drawn in by the wringing-out rollers of section II, whereupon it proceeds to a second dipping apparatus, which may be preceded by the action of a second pair of wringing-out rollers, a water-jet G, Fig. 4, being always interposed between two adjacent pairs of wringing-out rollers.

The operations set forth above go on in sections II III IV until the sliver reaches section V, Fig. 5, when proper water-jets Gand pairs of wringing-out rollers perform the last steps of the treatment. The sliver when finally wrung out is passed to the pulleys 61 62, Fig. 5, whereby it is wound on a core 63, which is kept in contact with said pulleys both by its own weight and by the weight of two metal disks 64:, one of whichnamely, the front onemay be removed with the view of drawing out the sliver-finished rollers, (cheeses,) which serve as a guide to the rollers which. are being formed. The whole is conveniently counterbalanced, so as to control the pressure under which the sliver-roller has been formed.
